Surge Protective Device LSPD PV 1000 Surge protection device’s for PV systems are to protect the inverter and the fixed installation, therefore PV SPD’s should be installed on the DC side of the PV system, before the inverter. These will always be Type 2 devices, unless the building has an external lightning protection system and the correct separation distance to BSEN 62305-3 has not been maintained, where you would install a Type 1 SPD. Features & Benefits Lightning & Surge protection for photovoltaic/solar systems Protects the DC side before the inverter LSPDPV1000 is a 1000V device Complies to IEC61643-1 and EN61643-11 Status indication as standard Din rail mountable Pluggable, replacement modules
